Gravesend was a county constituency centred on the town of Gravesend, Kent which returned one Member of Parliament (MP) to the House of Commons of the Parliament of the United Kingdom from 1868 until it was abolished for the 1983 general election. It is most notable for being a bellwether, with the winner of Gravesend (and its successor Gravesham) winning every election from 1918 through to the present day except for 1929, 1951, and 2005.
